AI Technical Summary
Technical Problem
Current methods for manufacturing surface-emitting lasers with single transverse mode output are costly and have low yield due to the difficulty in precisely controlling the oxidation opening diameter and requiring additional photolithography and etching steps.
Method used
A surface-emitting laser device with a distributed Bragg reflective layer having holes above the aperture, formed using an ultrashort pulse laser, to suppress multiple transverse modes, eliminating the need for additional photolithography and etching.
Benefits of technology
Achieves single transverse mode output with a simple, low-cost, and high-yield process by destroying distributed Bragg reflection characteristics in the holes, improving process reproducibility and maintaining device integrity.

Abstract
This invention provides a surface-emitting laser device that achieves single transverse mode output at low cost and high yield. [Solution] A surface-emitting laser apparatus comprising a first-type distributed Bragg reflective layer, an active layer, a second-type distributed Bragg reflective layer, and an oxide layer. The active layer is disposed on the first-type distributed Bragg reflective layer, and the second-type distributed Bragg reflective layer is disposed on the active layer. The oxide layer is disposed on one side of the second-type distributed Bragg reflective layer closest to the active layer, and the oxide layer has an aperture through which light emitted from the active layer passes. The second-type distributed Bragg reflective layer has a plurality of holes inside, which are located above the aperture and in the path of light emitted from the active layer. A method for manufacturing the surface-emitting laser apparatus is also provided.
